MediaMTX

Fixes and improvements

General

• playback: fix panic when MP4 muxer flushes with no samples (https://github.com/bluenviron/mediamtx/issues/5867)
• redact sensitive headers in HTTP debug logs (https://github.com/bluenviron/mediamtx/issues/5873)
• fix(recordstore): decode timezone offset minutes correctly (https://github.com/bluenviron/mediamtx/issues/5884)
• improve HTTP server performance (https://github.com/bluenviron/mediamtx/issues/5886) log incoming requests without cloning.
• prevent truncation of 64-bit values on 32-bit platforms (https://github.com/bluenviron/mediamtx/issues/5902)

RTSP

• add rtspScale parameter to inject Scale header on PLAY (https://github.com/bluenviron/mediamtx/issues/5800)
• client: switch automatically to TCP in case of H264 packetization-mode=0 (https://github.com/bluenviron/gortsplib/issues/1086)
• support VP8 streams with multiple partitions (https://github.com/bluenviron/mediamtx/issues/5426) (https://github.com/bluenviron/gortsplib/issues/1090)
• allow FU-A and STAP-A packets with H264 packetization-mode 0 (https://github.com/bluenviron/mediamtx/issues/5887) (https://github.com/bluenviron/gortsplib/issues/1092)

WebRTC

• skip unresolvable webrtcAdditionalHosts entries instead of aborting (https://github.com/bluenviron/mediamtx/issues/5845)

RPI Camera

• support encoding primary stream with MJPEG (2/2) (https://github.com/bluenviron/mediamtx/issues/5892)
• support encoding secondary stream with H264 (2/2) (https://github.com/bluenviron/mediamtx/issues/4485) (https://github.com/bluenviron/mediamtx/issues/5898)
• add unified rpiCameraH264Profile, rpiCameraH264Level params (https://github.com/bluenviron/mediamtx/issues/5894) These replace rpiCameraHardwareH264Profile, rpiCameraHardwareH264Level, rpiCameraSoftwareH264Profile, rpiCameraSoftwareH264Level.
• fix race condition that prevents decoding the stream (https://github.com/bluenviron/mediamtx-rpicamera/issues/109) (https://github.com/bluenviron/mediamtx/issues/5861) When a player immediately connects to a newly-created stream, SPS/PPS might not be available, neither in the SDP and neither in-band. Prevent the issue by always sending SPS/PPS in-band.
• improve performance by computing frame size once (https://github.com/bluenviron/mediamtx-rpicamera/issues/111)
• fix wrong timestamp being passed to openh264 (https://github.com/bluenviron/mediamtx-rpicamera/issues/114)

Security

Binaries are compiled from source code by the Release workflow, which is a fully-visible process that prevents any change or external interference in produced artifacts.

Checksums of binaries are also published in a public blockchain by using GitHub Attestations, and they can be verified by running:

ls mediamtx_* | xargs -L1 gh attestation verify --repo bluenviron/mediamtx

You can verify checksums of binaries by downloading checksums.sha256 and running:

cat checksums.sha256 | grep "$(ls mediamtx_*)" | sha256sum --check
